Skin tags, formally known as acrochordons, are small pieces of flesh that protrude from your skin. They’re attached through a stem or stalk. Skin tags are most commonly found in folds of skin around your neck, armpits, and groin area, and usually appear in people of middle age. While these growths aren’t painful, daily movement can produce friction, which may irritate them.
You shouldn’t experience any severe pain as the area heals, but you might deal with soreness or itching, Dr. Conrad says. Regardless of the type of mole removal you had, your doctor should instruct you on how to keep the area as clean and soothed as possible. For patients without stitches, Dr. Goldenberg recommends running a mixture of water and gentle soap over the wound at least once a day, gently patting it dry, then applying a thick ointment like petroleum jelly or an anti-bacterial cream before putting on a fresh adhesive bandage.
Repetitive friction and wearing tight clothes may contribute to skin tags in people who are overweight. According to a medical paper written by dermatologists in Spain, an obese patient, whose job required repeating lifting of her arms, developed a pattern of skin tags along her bra straps from the constant friction. Avoiding tight clothing if you are overweight is suggested.
Some other studies have suggested that skin tags may be associated with thyroid problems. An article published in December 2016 in the Journal of Evolutionary Medicine found that about 11 percent of people with thyroid issues had achrocordons, or skin tags. These patients tended to have a higher number of thyroid nodules and thyroid volume. This, they hypothesize, is because “skin tags and thyroid changes may be associated with high levels of circulating insulin.”
